:) My X3 has a stiff suspension because its a sports edition, very bumpy ride every time but I have noticed that if I put it on 4x4 mode everytime steering power is better suspensions a lot flexible. very good engine I could say uphill drive easy no effort at all. downhill drive with support from BMW technology by just simply pressing a button the car drives for you downhill just mind the brake acceleration let your BMW drives for you. in my opinion this car is great, I love the sound of the engine as if you own the road each and every time you step on the gas pedal. speed wise managed to do 125MPH no shaking (aintree race circuit), it follows the contour of the road and it can do more but the road is not enough for the speed. make sure tyres are always on the right pressure or else you are prone to spend more to gas or diesel. the disadvantage is that disc brakes and disc pads, and tyres are prone to wear and tear within 1-2 years depending on use of course...but in total I Love this car. a perfect family mid class SUV.
